HOSE-COUPLING.

SPECIFIGATIQN forming part of Letters Patent No. 526,174, dated September 18, 1894. Application filed June 18, 1894. Serial No. 5141 (N model.) i

T0 on whom it may concern:

Be it knownthat I, ALDEN L. BAILEY, a citizen of the United States, residing at St. Johnsbury, in the county of Caledonia .and State of Vermont, have invented certain new and useful Improvements in Hose-Couplings,

, water hose-couplings, and belongs to that class in which one section is a duplicate of the other. The invention consists essentially in the adjustable plug and socket connectionsg-the plugs of which are normally concealed within its section, all of whichwill be fully set forth inthe following specification and claims, and clearly illustrated in the accompanying drawings forming a part of same, of which- Figure 1,is a central longitudinal sectional elevation of my improved hose-coupling, as when connected, Fig. 2, being a face View of one section of my improved coupling, as if that section shown at the top, in Fig. 1, had its face exposed to View, Fig. 3, being a broken elevation in which the coupling plugs are concealed, as when in their normal position, and

shown in dotted lines;otherwise, this VlGW shows one section of the coupling in the same position as is that seen at the bottom in Fig. 1, which is also in the correct position to couple to the section seen in Fig. 2, by first placing them face to face.

Similar reference letters denote corresponding parts in all the. views.

Each section, A, of the coupling, has an enlargement, B, provided each with an exterior thread, 0, to which is fitted a threaded collar, the purpose of which will be hereinafter explained. Back of the threaded portion, 0, each section has a reduced cylindrical portion, D, back of which they are still further reduced, as at E, for the attachment of a section of hose. Each section A, has two sockets,

- F, placed at points diametrically opposite,

between which, and also arranged at points diametrically opposite, are twoperforations, G, in which rest the coupling plugs H, one end of which is provided with a suitable enlarged head, h, their other end being firmly secured at diametric points Within a collar, I, which is mounted, and adapted to move longitudinally, upon the smooth cylindrical portion, D, of each coupler-section.

The particular method by which the plugs u H, are secured to the collar 1, is notimportant; any convenient method which will rigidly attach them to said collar being all that can be desired. To this end, they may be closely fitted to perforations in said collarand a retaining pin put laterally through the edge of the collar and each plug, or the perforations in said collar may be threaded, and the plugs threaded to fit.

The object of the collar, I, and the reason for mounting the plugs H, therein, instead of mounting them in the section, A, is to guard against the coupling-plugs becoming accidentally bent and therefore inoperative, which would be a likely result of allowing said plugs to normally project beyond the face of either section a sufficient length, to

couple with the other.

A suitable spring, or springs, should be informed in the portion, B, or, an enlargement,

g, of the perforation, G, operating between the shoulder thus formed in said perforation, and the said collar.

The sockets formed in each section of the coupler for the reception of the couplingplugs of the other, are elongated, and form segments of a circle concentric with its section;the ends F, being large enough to receive, the heads, h, of the plugs, H, while the portions, f, are only sufficiently large to re ceive the stem portion of said plugs ;and to couple one section to the other, they are placed face to face, with the coupling-plugs, H, of one section opposite the sockets, F, of the other section, and the sliding collars, I, pressed toward each other and then turned slightly in opposite directions, which places the heads, h, of the coupling-plugs back of the smaller portions, f, of the sockets, thus effecting the coupling of the two sections. Then, in order to make a steam, or watertight joint, the threaded collars, or nuts, K, are turned slightly, in opposite directions, which moves them away from each other and causes them to bear against an annular flange, t, of the collar, I, which draws the heads, it, hard onto the sockets, f, and simultaneously crowds the gaskets, L, together.

Probably the most practical method of forming the sockets, F, f, is to provide an annular groove in the back of either part B, as previously mentioned, in connection with the springs, J, and as indicated by dotted lines in Fig. 2. The particular method by which the sockets are to be formed, however, is not a feature of the present invention.

Having described my invention, what I claim is 1. In a hose-couplin g composed of duplicate sections, adjustable coupling-plugs normally concealed and capable of protrusion, suitable sockets for the reception of said plugs, said sockets being elongated and smaller at one end than the other, and a threaded nut or collar for tightening said plugs within said sockets.

2. A hose coupling composed of duplicate sections, having each an externally threaded portion, an internally threaded collar mounted thereon, a sliding collar mounted back of said externally threaded portion against which said threaded nut may bear, suitable coupling-plugs mounted in said sliding collar and normally concealed within the externally threaded portion and capable of protrusion through and into the adjacent coupler-section, a suitable spring or springs for moving said sliding collar and retracting said coupling-plugs, and sockets for receiving the protruding ends of said plugs, all substantially for the purpose set forth.

In testimony whereof Iaffix my signature in presence of two witnesses.
